Does Overpronation Of The Foot Need An Operation

Overview

The anatomy of a normal foot allows for both to occur at the same time. Approximately 30% of the population have a normal foot. The remainder of people either overpronate (95% of abnormal feet) or oversupinate (5% of abnormal feet). The important thing to know is that all feet pronate and supinate, but abnormal feet do one of these things too much or at the wrong time. When the foot overpronates or oversupinates, several foot ailments can develop.Overpronation

Causes

Overpronation often occurs in people with flat feet, whose plantar fascia ligament is too flexible or too long, and therefore unable to properly support the longitudinal arch of the foot. People tend to inherit the foot structure that leads to overpronation. In a normal foot the bones are arranged so that two arches are formed, the longitudinal and the transverse. Ligaments hold all the bones in their correct positions, and tendons attach muscles to bones. If the bones are held together too loosely, they will tend to move inwards as this is the easiest direction for them to go. Over time the soft tissue structures will adjust to the misalignment and the foot will become permanently over-flexible, with a flat arch.

Symptoms

Because pronation is a twisting of the foot, all of the muscles and tendons which run from the leg and ankle into the foot will be twisted. In over-pronation, resulting laxity of the soft tissue structures of the foot and loosened joints cause the bones of the feet shift. When this occurs, the muscles which attach to these bones must also shift, or twist, in order to attach to these bones. The strongest and most important muscles that attach to our foot bones come from our lower leg. So, as these muscles course down the leg and across the ankle, they must twist to maintain their proper attachments in the foot. Injuries due to poor biomechanics and twisting of these muscles due to over-pronation include: shin splints, Achilles Tendonitis, generalized tendonitis, fatigue, muscle aches and pains, cramps, ankle sprains, and loss of muscular efficiency (reducing walking and running speed and endurance). Foot problems due to over-pronation include: bunions, heel spurs, plantar fasciitis, fallen and painful arches, hammer toes, and calluses.

Diagnosis

Pronounced wear on the instep side of shoe heels can indicate overpronation, however it's best to get an accurate assessment. Footbalance retailers offer a free foot analysis to check for overpronation and help you learn more about your feet.Over-Pronation

Non Surgical Treatment

The way a foot orthotic works is by altering the weight-bearing surface of the foot. The simulated foot improvement is only possible when standing still with full weight applied. Orthotics are of little help through most of the actual walking cycle. observationPatients may experience some symptom relief, but the orthotic cannot correct the internal osseous misalignment. Over-the-counter foot orthotics are usually of little help and wear out quickly. Custom-made foot orthotics, obtained through your doctor's office, are generally expensive. Though they last longer and have less chance of ill-effects than OTC brands, they still need to be replaced often. Over a lifetime, an individual can spend several thousands of dollars in total costs associated with orthotics and see little or no results. This is because orthotics only work when you are wearing them and do not treat the cause of the problem. In many cases, the external pressure points created by orthotics can cause more problems than solutions. Blisters, sore feet, sore joints and many other long-term complications can arise as a consequence of wearing orthotics.

Surgical Treatment

HyProCure implant. A stent is placed into a naturally occurring space between the ankle bone and the heel bone/midfoot bone. The stent realigns the surfaces of the bones, allowing normal joint function. Generally tolerated in both pediatric and adult patients, with or without adjunct soft tissue procedures. Reported removal rates, published in scientific journals vary from 1%-6%.
